Current clamps are used to measure the current circulating in a cable without
having to open the circuit. They are also used to insulate the user rom dangerous
voltages in the circuit.
Used with the installation tester C.A 6116, the accessory clamps are used to take
current measurements, earth measurements or selective voltage, power measure‑
ments* and the decomposition o signals measured in harmonics*.
The choice o clamp to use depends on the current value that is to be measured
and the diameter o the cables.
